Circulating air return
The circulating air (U) is sucked directly back into the
appliance.
If the heating appliance is installed in a stowage compart-
ment or similar, make an appropriately sized opening (approx,
2
200 cm ) for circulating air feedback.
Do not block air ducts to heating appliance!
Warm air supply and circulating air return
with outside assembly
Refer to installation variants Fig. 4 + 5 (Page 2).
The warm air duct and recirculating air duct between the
heater and the vehicle – especially in the area prone to stone
demage – must be made from flexible LF air ducting or, in the
protection zone, from LI air ducting (106 mm in diameter).
A protective casing over the entire heater system protects it
against damage and wea-ther conditions and simultaneously
serves as insulation.
Drill two openings with a diameter
of 100 mm. Apply sealing agent to
flange of both connector fittings
(41) and bolt to the openings on
the outside. Place the grid (47) in
the recirculating air duct between
the suction connection fitting and
the vehicle wall. Thread LFS wire
clamps (42) onto the air ducts (43).
Slide the air ducts over the heater
connection fittings (44) and the con-
nector fittings (41) and fasten them
with the LFS wire clamps (42). Seal
the joints with silicon paste.
Seal hollow double walls around the
air duct by putting two rolled sheet
metal strips (45) or lengths of pipe
between 97 an 100 mm in diameter
into the openings.
The warm air can be extended
inside the vehicle using LI air duct
(diameter 106 mm). To connect the
air duct, fasten another connec-
tion fitting (41) into the opening.
The two connector fittings can be
bolted together through the wall.
If you wish the warm air to be diffused inside the vehicle, an
air diffuser (46) can be fitted over the warm air duct (W) with
4 bolts.
Do not close off or restrict the opening for the recircu-
lating air duct!
The air diffuser (46) has 2 connections for VR duct (72 mm
diameter), neither of which must be closed off. The protective
metal sheet supplied (48) acts as a heat shield and must be
securely fastened over the air diffuser (46). Stowage protec-
tion can be provided in the form of another protective metal
sheet (49) fastened over the opening for the recirculating air
duct (accessory, part no. 39010-11500).
The warm air system is designed for each type of vehicle indi-
vidually, on a modular basis. There is an extensive accessories
program available (refer to brochure). Diagrams with optimum
installation suggestions for warm air systems in all of the most
popular motor home models can be requested free of charge
via the Truma service centre..
Fitting the control panel
When using control panels which are specific to the
vehicle or manufacturer, the electrical connection must
be effected in accordance with Truma interface specifications.
Any modification made to the Truma components pertaining
to this will lead to the cancellation of the guarantee and to the
exclusion of any claims for liability. The installer (manufacturer)
is responsible for providing operating instructions for the user
as well as for the labelling of the control panels!
When selecting the location, take note that the control panels
must not be subjected to any direct radiant heat. Length of
the connection cable 4 m or 10 m.
If installation is only possible behind curtains or in similar
locations with temperature fluctuations, a remote sensor for
the ambient temperature must be used (Accessories).
Installing the control panel with rotary switch
If flush mounting is not possible, Truma will supply an
on-surface frame (1 – part no. 40000-52600) as an acces-
sory on request.
Drill a hole 55 mm in diameter.
Plug the control panel cable (2) into
the control panel (3) and then fit the
rear cover cap (4) as a stress-relieving
device.
Push the cable through to the rear and
lay it to the electronic control unit.
Secure the control panel with four
screws (5) and fit the cover frame
(6) in place.
Truma offers side parts (7) in eight different colors for
finishing the cover frames (6) in a visually pleasing way.
Please ask your dealer.
Installing the control panel with slide switch
For existing installation sections.
Remove the cover screen from the installation section.
Plug the control panel cable (10)
into the control panel (8), feed it
to the rear through the installation
section, and lay it to the electronic
control unit.
Push the control panel (8) in un-
til the front face is flush with the
surface.
If there is no installation section present, the control
panel can be fitted with the flush-fitting installation frame
provided.
If flush mounting is not possible, Truma will supply an on-
surface frame (part no. 39050-11600) as an accessory on
request.
